is a relational database management system. It is a Open Source SQL
database provided by MySQL AB. MySQL is very fast, reliable, and easy to
use. It also has a very practical set of features developed in very close
cooperation with our users. MySQL was originally developed to handle very
large databases much faster than existing solutions and has been
successfully used in highly demanding production environments for several
years. Though under constant development, MySQL today offers a rich and
very useful set of functions. The connectivity, speed, and security make
MySQL highly suited for accessing databases on the Internet.
